4 Claims. (01. 18969) This invention relates to hinged hangers for detachable metal window-sashes suspended from the upper rails of metal window-frames, and to methods of forming the same.

The prime object of the present invention is to produce a simple and efficient hook-hinge hanger for pendant metal window-sashes having no component parts or accessories tobe assembled and attached, its members being integral respectively with the Window-frame and the sash; and to provide a method by which such a hanger can be readily formed out of the metal of the frame and sash rails.

A further object is to produce such integral hanger members by cutting and bending the metal of the rails cold.

Another important object is to provide a sash hanger member and method of forming it, without increasing the dimensions of, and especially without increasing the width of sash-rails of adequate size and weight, such as those commonly employed in the trade.

Minor advantages will become apparent from the following description of a preferred form of my hanger, and of the steps employed in the process of manufacture, reference being had to the accompanying drawing, in Which- Fig. 1 is an elevation of the inside of a glazed metal window-sash hinged and closed in its metal window-frame.

Fig. 2 is an enlarged sectional elevation taken on line 22 of Fig. 1.

Fig. 3 is a detailed elevation of the inner side of the hinge-hanger shown in Fig. 2.

Fig. 4 is a bottom view of the top rail of the window-frame showing the hanger members pendant therefrom.

Fig. 5 is a plan view of the top rail of the sash showing the hanger member formed thereon.

The present invention is especially suitable for use in steel-framed basement windows, such as shown herein, but it is adapted to any top-hinged metal window of a construction permitting its application; and it is peculiarly fitted to meet the demand for a low-priced and eificient metal window having a detachable sash.

In the drawing the reference numeral 1 indicates the window-frame of low-carbon steel, or other suitable metal, such as frequently set and secured in window openings in basement and other walls, being formed of angle-bar as shown, or of T-bar if preferred; and it usually has anchoring wings 2 on its sides. The sash framing 3 is fashioned of T-bar of a smaller size than that of the frame 1, but of similar metal, and both of said frames have the stem parts of their T-bars, H

or wings of their angle-bars as the case may be, projecting inward as shown. The sash is glazed by securing panes of glass 4 against the inner flanges of its T-bars by suitable clips, not shown, and usually by putty also as shown at5, Fig. 2; and an appropriate sash-lock at its lower edge is required.

The hook member 7 of the hinged hanger is an integral part of the horizontal inwardly extending wing 6 of the top rail of the fixed windoi frame 1; being formed therefrom by cutting out three sides of, and bending sharply down at a right angle a substantially rectangular leaf, or tongue, of the said wing, and then bending the lower and unattached portion of the leaf inwardly and upwardly in the form of a hook, as best shown at '7 in Figs. 2, 3 and 4.

These operations on metal of the quality commonly employed for window-frames can be readily performed without heating the metal or fracturing it. In forming the hook '7 sufficient space must be left between its termination and the under side of the frame wing 6 to pass therethrough the sash member of the hanger.

The sash member of the hanger, which serves integral with the stem leg 8 of the upper T-rail of the sash-frame 3; and is formed by cutting out of the stem 8, adjacent to the flanges of the T-bar, three sides of a rectangular leaf 9, and bending the leaf sharply upward at its inner attached end or root and downward near its medial section, thus making a reverse bend, so that the leaf 9 when fully formed into an eye-bracket will stand with its upper end portion further inward than its root to properly engage the hook '7. The T-stem 8 is usually so narrow as compared to the width of metal required to form an operative hook '7, that it is diflicult to make the leaf 9 long enough to reach inward and upward to engaging position with the hook, and yet retain sufficient metal in the edge of the T-stem at the root of the leaf.

The inner edge 10 of the stem 8 of the T-rail at and abreast of the root of the leaf 9 is then bent downward and outward, which bends coincidently the root of the leaf upward and inward until the free end portion of the leaf stands upright, as shown in Figs. 2, 3 and 5. This bending or twisting and consequent tilting of the edge 10 and the leaf 9 elevates the leaf somewhat, and also strengthens the spanning T-stem edge in the direction of its greatest stress in service.

A horizontally disposed rectangular slot 11 is punched out of the leaf 9, so as to leave a bearing-bar l2 spanning the slot at the upper and unattached end of the leaf, said bar being adapted to be inserted and to turn in the socket of the hook 7. Thus the leaf 9 becomes the eye-bracket sash member of the hinge-hanger, and all the steps of its construction are cold metal cutting and bending operations. Moreover, a practical eye-bracket 9 of sufiicient height and positioned far enough inward toproperly engage a hook 7, such as formed in the manner described, can-be fashioned thus integrally from T-bars of the small size usually employed in sash framing; which result appears to be impossible otherwise without unduly increasing the size of the T-bar, or hot-forging it.

The sash 3 is hung to, or disconnected from the window-frame 1 by opening it wide, or raising it in a horizontal position, as indicated by dotted lines in Fig. 2, whereupon the eye-brackets 9 of the sash may readily be engaged with or removed from the hooks 7 of the fixed frame. The inclosing edges of the slots 11 embracing their respective hooks '7 prevent disengagement of the sash in any but a wide open position.

In order to assure a tight closure of the sash 3 against the frame 1, and to relieve the hooks 7 and brackets 9 from lateral strains, jambs or keepers 13 may be provided on the under side of the wing 6 to receive and hold the flange 14 of the top T-rail of the sash against the pendant leg 15 of the top rail of the frame 1. Such a keeper can be cold-formed, as shown, by cutting from the wing 6 and bending down to a right angle a suitably shaped and positioned tongue or leaf 13, so that the flange 14 will, as the sash closes, swing up between the leg 15 and the tongue 13, preferably engaging the outer edge of the tongue as shown, although the tongue may be set sidewise to the flange 14 if desired.

In the practice of the invention modifications may be made in the detailed forms and steps herein set forth, but it is intended that the patent shall cover all modifications within the proper scope of the invention.

I further point out and distinctly claim as my invention:-

1. A hinged sash hanger for metal windows comprising a hooked hanger pendant from and cold-formed integrally out of the metal top rail of a window-frame, and a tongue-like eye-bracket formed on the T-bar top rail of a metal sash and adapted by bending and slotting to engage the hooked hanger.

2. A hinged sash hanger for metal windows comprising a hooked hanger pendant from and formed on the metal top rail of a window-frame, and an upright reversely bent leaf member coldformed out of and integral with the metal T-bar .top rail of a sash-frame and having an aperture therein to receive said hooked hanger.

3. A hinged sash hanger for metal windows comprising a hook pendant from and formed on the metal top rail of a Window-frame, and an upright bracket provided with an aperture to receive the hook cold-formed with suitable bends on the T-bar top rail of a metal sash, the root of said bracket together with the sash-rail edge abreast of it being bent upward and inward into a diagonal position.

4. In a hinged sash hanger for metal windows, a hook pendant from the metal top rail of a window-frame, an upright member on the top rail of a metal sash fitted to engage the hook to form a hinge-hanger, and one or more tongue-like keepers depending from and cold-formed integral with the top rail of the window-frame, said keepers being adapted to bear against the sash rail and to co-operate with the hinge-hanger in holding the sash tightly against the frame when closed.
